It would be nice to know if we share the information that how much is the international call charges you have to pay to your service provider? We can then understand that whether there is any relation in international mobile telephony charges among different coutries?
I live in the US and I have Cingular as a provider. My husbands family lives in the UK. A 30 minute phone call runs about $30 to $40 on the average when he makes a call to them using the cell.
I think it would be darned near impossible to come up with a figure because there are all sorts of different plans in different countries, and very little hard information. Unless someone wanted to spend countless hours/days/week amassing it.
